The object of this invention is to provide a machine for drying laundry or other soap so that the soap will have a hard outer surface which will keep the moisture within the body oi? the soap, which is particularly advantageous in soaps used for laundry purposes. V

In the accompanying drawings z-higure 1, is a sectional plan view of my improved soa'p drying apparatus; Fig. 2, is a longitudinal sectional View of part of the drier; and Fig. 3, is a transverse sectional view on the line 33, Fig. 1. g

A is a casing having a longitudinal passage B throughout its entire length, closed at both ends by doors 6 movable 1n and out of position in any suitable manner.

0, 'c are tracks located a given distance apart-three sets in the present instance-- which guide the trucks on which the soap to be dried is mounted. These trucks may be of any of the ordinary forms used in carry-' ing materials, but which I preferably so design that the soap can be readily stacked thereon so as to allow the currents of air to pass through the stack orpile on the truck, as indicated in Figs. 2 and 3.

At each side of the passage B are chain:

hers D, D, D D D containing fans 1E mounted on shafts E adapted to suitable bearings and rotated by power in any man ner desired. These fans are altetely ar-.

ranged on o posits sides of the passage B, as clearly il ustrated in Fig. 1. The series of chambers on each side of the passage B are divided by vertical partitions d, and in the two compartments at the forward end of the apparatus at each side oi? the passage are steam pipes E so as to warm the air as it passes throu h these particular compartments. The en compartment D at the discharge end of the apparatus is open at the bottom to the atmosphere, so to allow the fan E in the compartment to draw fresh air into the drier and force it across the longitudinal passage B into the receiving an her opposite to it. The air is dra from the action of warm air.

this receiving chamber by the next ten which is r on the side opposite to the first mentioned fan, and this fan forces the air across the passage in the opposite direction, as indicated by the arrows. The air enters the second receiving chamber and is carried by the third fan across the passage B into the final receiving chamber D which is open at the top to allow the air to pass from the drier. The compartment D has an inlet opening in the floor, and the fan E in said compartment draws the air through said opening and forces it across the passage B into a receiving chamber of the. second series, and this fan forces the air across the passage in the opposite direction. where the third fan takes it and again forces it across, and so on throughout the length of the drier until it escapes from the chamber D at the front of the drier.

The last chamber on one side, and the next to the last chamber on the opposite side have steam pipes 18 therein which warm-the air, as above mentioned, and consequently the soap as it enters the passage is subjected to This air partly dries the soap and as the soap travels through the passa c it comes in contact with the cooler air an finally cold air is blown onto the stacks of cakes of soap, which forms a hard'crust on the cake, and this hard crust retains the moisture within the body of the cakes of soap.

The trucks can be conveyed through the passage B by any suitable means. Tn the present instance, I have shown conveyer chains 1 which are driven from any source of power, and these conve er chains have lugs or other projections w ich engage the trucks and move them forward, one truck proportioned that they: can be piled onev u on another on the trucks. The cleats a ot the several trays, as indicated in the drawings, are in line one with another and are also in line with the permanent partitions of the drier. So that, when the trucks are moved forward by the mechanism at the hard as the exterior surface.

' formed which is desirable for stamping and inlet end of the drier, they will be moved thelength of one section and the series of cleats form vertical partitions throughout the entire length of the drier and these par-- titions aline with the permanent partitions in the side compartments, and when the air is forced by the fans across the central passageway containing the trucks it is confined by the cleats, which from the vertical partitions, to a certain extent and the air must travel directly across the drier.

The mechanism is so arranged and the trucks are of such a size that when one truck enters the drier another truck is discharged therefrom.

While my invention is particularly adapted for drying soap it will be understood that it may be used for drying glue and like material, where it is desired to have the body of the material being treated not as The soap when it reaches the drier is in W hen it is introduced into the drier it is subjected ,to the action of the currents of warm air an this immediately warms the outer surface of the cakesot soap which are spaced apart on the trays and, after being subjected for a given time to the Warm air, they are inter mittently moved into the path of the cold air currents and the warm outer surface of the cakes is chilled and a thin hard crust is Wrapping purposes.

1 claimsl. The combination 1n a soap drier, of a casing hav ng a longitudlnal' passage throughout its entire length; chambers on arranged within the said chambers on eac side of the passage; means for driving the fans; inlets for cold air and outlets for air; means for heating the air at the for ward end only of the drier; and carriers for the soap adapted to travel through the longitudinal passage so that the soap in its passage through the machine is first subjected to the currents of warm air, which heats the outer surfaces of the cakes, and is then subjected to currents of cold air, whereby the warm, outer surfaces of'the cakes of.

rails on .which trucks are mounted; power driving means for propelling the trucks through the drier chambers oneach side of the. longitudinal passage; fans in said chambers, said fans being alternately arranged on either side of the casing so that air admitted at one point will be forced across the chamber in one direction hy one set of fans, and forced across the chamber in the opposite direction by anotherset of fans, with means for heating the air at the entrance end of the drier so that the soap will be first dried by warm airin the first part of the drier, and finally dried by". cool air before being discharged from said drier.

3. The combination in a drier,'of a casing having a central chamber; side chambers; transverse partitions in'the side chambers; fans for blowing air across the central chamber; and trucks mounted in the central chamber having partitions which aline with the transverse partitions inthe side chambers, so that the air is confined as it is blown across the drier and through the trucks.

4. The combination in a drier, of a casing having a central chamber; side chambers;

transverse partitions in the side chambers; fans in the side chambers for blowing air across the central chamber; trucks; a series of trays mounted on the trucks; vertical cleats on each tray; the cleats being a distance apart equal to the distance apart of the transverse partitions so that when the truclrs are intermittently moved through the central passage the cleats form, with the transverse partitions,flues for the passage of air.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
